This roleplay interests me for three reasons: 

One, it's a science fiction roleplay. Science fiction is one of my favorite writing genres. 

Two, It takes place on a single planet, which is relatively uncommon when it comes to science fiction NRPs and NRP-hybrids. Small scale is best scale. 

And three, it puts strong emphasis on character interaction and, if I'm not mistaken, character development. Large-scale NRPs seem to always go over terribly for me, because playing a single planet in a science fiction NRP makes you a prime target for invasion. This becomes overbearingly annoying when you're trying to focus on something other than who has the strongest space fighter or the most powerful army of steroid-infused space marines--if you know what I mean.

Before I go into some light detail about my idea, is there any information on the Tkrai other than that which is listed in the OP?
